Kirby 64
Pop Star: Level 3

This level isn't quite straight left-to-right ... it has more of a curving feeling to it. You begin outside a building by a drawbridge. You go in and up some stairs. Next You go up and around a ledge. When you go back inside, be sure to have the double-cutter equipped: you get the first shard by using it.

When you get to the circular track, right above your head is a ledge with the next shard.

Go around the circular inside here. Use the chains to climb up to the roof. Up on the roof is your final friend, King Dedede. Fight him off, and you get the final shard and his friendship.
